The HYDROGEN ATOM; ATOMIC ORBITALS Form

Instructions and help about THE HYDROGEN ATOM; ATOMIC ORBITALS

in this video we're going to talk about orbitals energy levels sub-levels quantum numbers and things like that now an orbital is simply the most probable location to find an electron so let's say this is nucleus we're going to consider the bohr model of the atom so i'm going to draw circular orbits so this is going to be the first energy level n equals 1 and here we have the second energy level n equals two and here's the third energy level an equal stream an electron that occupies the third energy level has more energy than one that occupies the second energy level n represents the principal quantum number it describes the size and the energy of that orbital so as n increases the distance from the nucleus increases as well so electrons that are closer to the nucleus exist at lower energy levels electrons that are further away from the nucleus exist at higher energy levels so that's the first quantum number that you need to be familiar with so n is the principal quantum number so keep
